I have installed Adobe Acrobat 6 Pro. There is no plot device listed for PDF writer. I tried to create a plotter however, it asks for an .hil file. I thought it would be pretty automated as it is in my other applications where I have PDF icons. How to I set up my plot manager to create PDF drawings? I also tried importing the file to Acrobat. Acrobat has an error message that says the file is from an application not on my computer. Although I did not create the file, it was sent to me. I can review and change in LT2004. What do I do next?
